Find Duplicate Values in the Gridview using Javascript

I have a following requirement. I have a Gridview contains two columns:

Model Name	Model Description
Model A	Model A Desc	Edit Update Cancel
Model B	Model B Desc	Edit Update Cancel
Model C	Model C Desc	Edit Update Cancel

Let's whe开发者_Python百科n user click Edit link on model C then when he type Model B (Replace 'Model C' with 'Model B') then on Update link I would like to warn the user that Model B already been defined. I would appreciate your help. For your information both txtModelName and txtModelDesc are template fields.

You can user inside of template field and call a function where in there which does all of the checks you need.

If you intend to do it through javascript, I guess you will have to loop through dom entries for grid and validate.
